One object of my present invention is to avoid the necessity of removingthe stylus i as is required in the machines now in use, by providing anim roved stylus formed. from sheet metal and aving a plurality ofclosely-aneuged reproducing I nstructed, and a new reproducing pointbrought into operative position by a slight rotary move. ment of thedisk. i

In this way the stylus', though mounted to becapable of rotation to successively bring the several oints intooperative osition, is nevert eless clamped sufficient y firmly to thearm 23 to cause it to be rigid therewith for the purpose of the recordto the diaphragm of the sound box, and as before stated, the stylusitself,

because of itsconstructi'on, is rigid in the direction of sound-wavedeflection, so that none ofthe delicate, fine'sound waves can be lost byflexibility, but are positivel conveyed to the sound boxdia ,-w 'le atthe same time the stylus is dbxil fi tion to Kield to'the oughness andunevenness of t e bottom of the sound-wave grooves this roughness to thesound-diaphragm.

In a device of this character it is essential that when the stylus isturned to bring any one of thereprod'lieing points to operativeposition, it must'be-accurately turned the proper distance to preventanyof the other points interfering able this to be quickly, readily andaccuprovide means for turning the stylus one oint at a time. Thisconsists of a lever 40w ich extends through and is journaled in theblocklO, the end thereof adjacent the stylus being provided with a crankarm 38 carrying a laterally-extending pin 39 ada ted to elegage betweenthe points of .the nee is when the handlc'is rotated. In the position.shown in Figs. 1 and 2 this handle is portion of the stud the'wave-soundinundations In practice, this instrument, and. grating or grindingmember 36 is rotatably' mounted in a'swinga laterally turned ear in adirec-- oints are placed as near-:to-

The crank arm pin or stud 39 will engage hat-wean the points ofthe stylus when the lever 40 is rotated, and asin'glc rotation thereofwill cause the stylus to be rotated a portion having a circular ing ofaplurality of radially-extending vantage in the hands right anglesthereto for what I consider at this time the most desirthe rou distanceto bring a succeeding point into proper operative position in respectto. the record. I

As previously stated, although the stylus is capable of rotation tobring the points thereof into successive o eration, it is clampedsufliciently'tight to e rigid so ,far as transferring the inundations ofthe sound waves to the sound diaphragm is'concerned, and this frictionalclamping of the stylus assists in the positioning of the points by preventing it from'throwing by or beyond the distance it .is actu llymovedby the crank arm pin 39.

A stylusof the construction here. shown will avoid to a very largeextent what is considered by many to be an objection to that class ofinstruments which require the remo val of the stylus and thesubstitution of a ,-new one for each tune, and will place this ad ofthe-user at a considerablereduction over the cost of using the ordinarysingle needle, and this is due to the tthat the K rmed from thin sheetmetal capable of be,- ing "produced by stamping y it therefrom, vi-hile'atthejsarne time :it has the advantage yof rigidity in the properdirection to avoid the lossjof anyof the delicate sound waves, and'fleXibilit" in the direction liness'and irregularities of thebottornof. e wave grooves;

I am aware that flexible needles for sound producing machines-of. thecharacter herein escribed have been heretofore devised, but sofa'r asl'know these need been xflexiblef iin all-directi there wouldof necessitybe some loss in conveyin'g the delicate'soundwayes to the sound 1ftheflexibil ty .of the needle gs'orstvluses have is constructed to be infteodire'ction of deflection-of the sound waves, and flexible in adirection at the purposes hereinbeforeex lained,
